Milwaukee 48-89-2711 Black Oxide Jobber Drill Bit 6 in

Product Description

The MILWAUKEE 48-89-2711 is a black oxide jobber length drill bit engineered for demanding jobsite conditions. At 6 inches in length, it features a thicker-than-standard web core that resists side-load breakage and extends service life in high-cycle applications. The 135-degree split point tip starts on contact without walking, delivering fast, accurate hole placement. A parabolic flute geometry clears chips and debris quickly, reducing heat buildup during extended drilling operations. The black oxide coating adds lubricity and corrosion resistance. Licensed tradespeople and skilled tradespeople across construction, mechanical, and maintenance trades rely on this bit for consistent performance with portable drills.

The 48-89-2711 is suited for general-purpose jobsite drilling in metal, wood, and similar materials. The reduced shank diameter allows use in standard 3/8 inch chucks, making it compatible with a wide range of portable corded and cordless drills. The 3-flat Secure-Grip shank design prevents slipping in the chuck during high-torque drilling. It performs well on flat and curved surfaces alike, requiring less feed pressure than conventional jobber bits. Ideal for plumbers, electricians, HVAC techs, and general contractors who need a reliable everyday drill bit on the job.
